Are you gonna let Izzy hook up Takato's D-Arc to his laptop through a USB cable, to maybe replicate the functions of the D-Arc into his database, maybe modifying and upgrading the Digimon Analyzer in his laptop, into an improved version?

Maybe you could let Takato draw a Card through the Card Reader of his D-Arc, while it's hooked up to Izzy's laptop, making Izzy gain more information.
